Compare the two measured values with the specified values, replace the shims concerned.

Clearance setting (in mm), cold:

  • Intake: 0.10
  • Exhaust: 0.25

REPLACING THE SHIMS

This operation requires removing the intake and exhaust manifolds (see chapter 12 Intake/Exhaust manifolds).

Place the valve concerned at full opening (by turning the engine in the normal direction of rotation).

Insert tool Mot. 1366-01 into the port concerned.

For intake valves

Turn the engine in the normal direction of rotation until the valve bears on tool Mot. 1366-01 (camshaft rotation of 90° from the full-open position).

For exhaust valves

Turn the engine strictly in the reverse direction of rotation (to avoid engine lock-up) until the valve bears on tool Mot. 1366-01 (camshaft rotation of 90° from the full-open position).

Remove the shim using a screwdriver and a magnetic pick-up tool.

NOTE: when refitting the shim, remove the oil from the bottom of the bore (C) of the tappet.
